(NaturalNews) Hospital antibiotics have become one of the most over prescribed "medicines" today. As a result people have ruined their digestive systems, and ironically, have lowered their natural immunity to all types of infections in the future. Get rid if infections without the digestive destruction, with these five powerful natural antibiotics.

GarlicGarlic has been used medicinally by cultures around the world for thousands of years. In fact, it was used in the 1700s to ward off plague.

Garlic possesses potent antibiotic, antiviral, antifungal, and antimicrobial properties and is able to help protect and facilitate removal of unfriendly bacteria. It is also very high in natural antioxidants that destroy free radicals, which also supports a strong immune system.

The active ingredient in garlic, allicin, is the key component to killing and warding off harmful bacteria. Crush it to activate these compounds, and eat it raw, in a warm tea, or in lightly cooked food.

Colloidal silverColloidal silver has been known as an effective antibiotic for centuries. In the early 1900s, Alfred Searle, founder of the Searle pharmaceutical company, discovered that it could kill the most deadly pathogens.

Searle stated that applying colloidal silver to human subjects has been done in a large number of cases with astonishing results. The main advantage was that it was rapidly fatal to microbes without toxic action on its host.

Recent research has also stated that colloidal silver can destroy antibiotic resistant microbes like MRSA, the bird flu, and SARS.

Oil of oreganoOil of oregano takes care of pathogenic bacteria without disrupting beneficial bacteria. It is also antiviral and antifungal which makes it a powerful three-in-one combination that rivals pharmaceuticals while not encouraging antibiotic resistance.

The key antimicrobial ingredient in oil of oregano is carvacrol. You should ensure that your source is at least 70 percent carvacrol content in order to be effective.

EchinaceaEchinacea has been used to treat a wide variety of infections for hundreds of years. Traditionally, it was used to treat open wounds, diphtheria, blood poisoning, and other bacterial related illnesses.

Today, this potent herb is used mostly for colds and flu, due to its ability to destroy the most dangerous forms of bacteria such as staphylococcus aureus, which causes deadly MRSA.

Manuka honeyPerhaps the most palatable antibiotic comes in the form of manuka honey. Applied topically it can kill a wide range of pathogens including MRSA and flesh eating bacteria. It was also found that the treated bacteria did not build up any resistance, which would eventually render manuka honey ineffective.

This is certainly not an exhaustive list of natural antibiotics, but a great start for an all natural pharmacy. Also consider reishi, pau d'arco, una de gato, olive leaf extract, cloves, turmeric, and even lemons to round out your antibiotic arsenal.
